HOT-AIR REGISTER.

SPECIFICATION forming part of Letters-Patent No. 429,968, dated J' une10, 1890. Application tiled January 17, 1890. Serial No. 337,224. (Nomodel.)

T all whom, .it may concern.'

Be it known that I, LAFAYETTE ScHAUcK, a citizen of the United States,residing at Rochester, in the county of Monroe and State of New York,have invented new and useful Improvements in Hot-Air Registers, of whichthe following is a specification.

The purpose of this invention is to provide certain improvements in theconstruction of hot-airregisters of the kind ordinarily set in the sidewalls and vertical partitions of buildings heated by furnaces, onepurpose of the invention being to provide a connection between thescreen or face, the box, and the intermediate body, which shall beentirely airtight, while the weight of the parts and the labor andexpense of manufacture shall be materially diminished.

It is my further purpose, also, to provide a light, simple,easily-operated, and inexpensive construction and combination of parts,whereby the volume of air delivered from the register may be Icontrolledwith accuracy without obstructing the passage and in such manner as todirect the hot-air current into the room.

It is one purpose of my invention, also, to provideA means whereby anadjustment may be made of the damper for cutting the aircurrent oiialtogether or for admitting its pas-.

sage to any degree required, the adjusting devices being of theA mostsimple and inexpensive form, of leasyoperation, and of the minimumnumber of parts, the construction being such that the damper is held atany angle without employing stop devices or similar adjuncts and iu suchposition as to deliver the air through the screen or face wit-houtmaterial obstruction Lor diminution of and claimed, reference being hadto the accompanying drawings,in which- Figure l is a central verticalsection of a register constructed in accordance with my invention, thesection-line being indicated by the line @c o; in Fig. 2. Fig. 2 is afront elevation of the register, a portion of the screen being brokenaway. Fig. 3 is a detail perspective of the damper or valve detachedfrom the other parts. Fig. 4. is a detail perspective of the valve-frameor valve-box, showing the valve-lift in operative position. Fig. 5 is adetail section showing the construction of the j ournal-.bearing for thevalve-lift. Fig.`

6 is a perspective View of the body of the register separated from thebox.

In'the said drawings, the reference-numeral l indicates the hot-air box,which is form ed of tin or other suitable material in the ordinarymanner and placed in the wallsat those points where the heated air is tobe conducted from the furnace. Upon the upper end of this box andsurrounding the same is mounted a rectangular metallic frame 2, securedin position by bolts 3, passing through apertures l in its ends andthrough openings in the metal of the box. This frame, which constituteswhat may be termed the valve-box, is provided at its two rearward angleswith lugs 5, which receive the journal-pins (5 of a valve or damper 7,consisting of a flat metallic plate, which entirely closes therectangular opening surrounded by said valve-box. To provide for theready mounting of the valve one of its journal-pins is formed of aseparate piece and provided with an ear S, whereby it is detachablyconnected with the valve by means of a bolt 9. The valve or damper 7 israised and lowered to open and close the box by means of a transverserock-shaft l0, provided with a cam 12, preferably placed between thecenter andthe rear end of the shaft that it may have a greater throw orlift. The rock-shaft is composed of a plain cylindrical metallic barlying in semicircular openings or bearings in the edges of thevalve-box, and provided with a collar 13, lying immediately within thefront wall of the box to prevent longitudinal movement of the shaft bythe push of the inclined valve upon the cam. Upon said shaft in the IOOsaine plane with the front wall is formed a nipple or lug 14, which actsas a stop, the front wall being cut away upon each side of the shaft toform shoulders 14, against which the lug 14 strikes as the cam reachesits highest and lowest point of adjustment. As the shaft is held downwithin its semicircular seat by the means hereinafter described,thisstop provides a simple preventive against turning the cam so far as todrop the valve with a noise, and on the other hand it serves to preventthe cam from being thrown out of proper position with relation to thevalve. Upon its outer end the rock-shaft is provided with a crank 15 orother suitable means whereby it may be operated. The cam 12, beingplaced as described, has a frictional contact with the inner face of thevalve,which holds it at any point to which it is adjusted, thusdispensing with any form of stop to hold the shaft against the pressureot' the valve when the latter is partly raised. Upon the back of thesaid valve is formed or mounted a lug 1b', which arrests its upwardmovement at. the proper point.

The register box or casing 17 ,which is practically a contin nation ofthe box 1, is mounted on the valve-box 2, its lower open end being'slipped over its exterior and resting upon a flange 1S, formed thereon.The front of this box is provided with the usual opening, and the edgesof the metal surrounding the same are turned outward, as shown inFig. 1. Upon the front of the register-box is mounted the body, whichconsists of an open rectangular metallic frame 19,provided with anexterior iiange having lugs 20,which receive the bolts or rivets 21, bywhich it is secured. This flange is also provided with a notch, whichstraddles the rock-shaft 12 and aids in holding it securely in itsbearings in the valve-box. This body may be of any suitable depth and isset in the plastering, with which the outer edge is flush, or nearly so.Just within its exterior edge it is provided with lugs 22, havingbolt-openings 23, provided with a female screw-thread. As shown in thedrawings, these lugs are placed upon the ends of the frame only; `butthey may be located upon the sides only or upon the ends and sides also.

The numeral 2l indicates the face or screen of the register, which iscast with any ornamental open-work and mounted upon the body 19 byscrew-bolts 25, which engage the openings 23 in the lugs 22. The face orscreen is provided with an inwardlyinclined iiange 2G, which restsagainst and is drawn closely up to the outer face of the finished wall.'lhe advantages of this construction will be readily apparent to all whoare ac quainted with the art to which it pertains. It forms anabsolutely air-tight connection between the register box or case 17 andthe wall in which it is set, and this result is attained withoutadditional labor, skill, or care upon the part of the constructer, whosework is materially expedited and lightened, since it is only necessaryto set the box in such manner as to enable the attachment of thebody-frame 19 and lay the plaster Iiush, or substantially so, with theexterior edges of the same.

The valve or damper 7 forms a simple, inexpensive, and easily-operateddevice, whereby the volume of hot air supplied by the register may beheld under perfect control and the heat of the room regulated to theexact degree required. The parts are fcw, light, and easily adjusted,andare incapable of perceptible wear, breakage, or disorder. Thevalvebeinglocated as shown and being hinged or pivoted to the back ofthe valve-box, and there being a single valve o nly in place of thr'eeor more, as is usually thc case, the air is enabled to pass withoutdetention, and is directed by the valve toward the center of the room inall positions of the latter. The construction is exceedingly economicaland simple, the parts are few in number, and may be readily set andarranged in working order by a person of ordinary skill.

Theinvention is particularlyadapted to sid e wall or vertical partitionregisters only, and I do not limit myself to the use of the particularconstruction of rock-shaft and cam shown and described for operating thevalve, as I may substitute other and equally simple means foraccomplishing the same purpose.

In fines or hotair boxes which run from story to story the openings areformed in thc usual manner at the proper points, and where theconstruction of the wall or other circumstances require it a horizontalbox may be joined to the flue to extend to the point where the registeropens into the room; but in all changes of this character the body 19 isattached in the manner already described.

IVhile I have described this invention as adapted to systems of heatingby hot air, it is evident that it may be used for indirect radiationeither by steam or hot water.

Vhat I claim is- 1. In a hot-air register, the combination with thehot-air box, of a valve-box consisting of a rectangular metallic framesurrounding the top of said box and secured thereto, avalve or damperhinged or pivoted at the rear of said valve-box, and a centraltransverse rock-shaft journalcd in semicircular notches in said valveybox or frame and having a cam raising and lowering the valve,substantially as described.

2. In a hot-air register, the combination, with the register box orcasing, of a body composed of an open metallic frame of suitable depthhaving exterior lugs which receive the bolts attaching it to saidcasing, and a facing or screen mounted on the exterior ed gc of the bodyand fastened thereto by screwbolts engaging interior lugs on said body,thc face or screen being provided with an in- IOO IIO

wardly-inclined ange projecting beyond the edge of the body,substantially as described.

In a hot-air register, the combination, with the hot-air box, of avalve-box surrounding and secured to it, a valve or damper hinged orpivoted at the rear of said box, a central transverse rock-shaft havinga cam lifting and lowering said valve, and a register box or casingslipped upon the exterior of the valve-box and resting upon a flange orrib thereon, substantially as described.
